[jira] [Commented] (HADOOP-11026) add FileSystem contract specification for FSDataInputStream and FSDataOutputStream#isEncrypted

["Steve Loughran (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-11026?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14117323#comment-14117323 ] 

Steve Loughran commented on HADOOP-11026:
-----------------------------------------

This looks good, though if there are plans to extend {{FileStatus}} with some encrypted flag, that should be integrated in the spec.

e.g if the status says "encrypted" then the stream's {{isEncrypted()}} flag must  be true, and vice-versa.

This could then be added as a new test for all filesystems, HDFS and non-HDFS.

Also, though it could be a separate JIRA, I'd like to see the contract tests for the Crypto support. HADOOP-11042 shows that it isn't consistent with HDFS, something those tests would have thrown up.

> Following on to HDFS-6843, the contract specification for FSDataInputStream and FSDataOutputStream needs to be updated to reflect the addition of isEncrypted.
